چکیده
مناطق پرورش موز در اقلیمهای نیمه گرمسیری بین 20 تا 30 درجه شمالی یا جنوبی خط استوا واقع شده است و با توجه به اینکه استان سیستان و بلوچستان در عرض جغرافیایی 25 تا 31 درجه شمالی قرار گرفته است، میتواند برای کشت موز مناسب باشد. در همین راستا هدف اصلی این پژوهش شناسایی توان اقلیمی استان سیستان و بلوچستان برای کشت درخت موز با استفاده از نمایههای اقلیم کشاورزی است. در این پژوهش نمایههای درجه روزهای رشد، درجه روزهای موثر بیولوژیکی، مجموع دماهای فعال، اختلاف تجمعی دما، کمبود فشار بخار آب و تبخیر و تعرق پتانسیل با استفاده از دو روش سلسله مراتبی و منطق بولین اقلیم استان مورد ارزیابی قرار گرفت. نتایج پژوهش نشان داد با روش سلسله مراتبی 17 درصد از مساحت استان (شهرستان های دشتیاری، چابهار، کنارک و زرآباد و بخش هایی از جنوب شهرستانهای راسک، قصرقند و نیکشهر) برای کشت موز بسیار مناسب و 8 درصد برای کشت موز مناسب میباشد (نیمه شمالی شهرستانهای سرباز، راسک و نیکشهر). همچنین نتایج این پژوهش نشان داد در منطق بولین 10 درصد از مساحت منطقه مورد مطالعه (شهرستانهای دشتیاری، چابهار، کنارک و زرآباد و بخشهایی از جنوب شهرستانهای راسک، قصرقند و نیکشهر) برای کشت درخت موز در استان مناسب میباشد. مناطق کشت موز در حال حاضر کمتر از 1 درصد مساحت استان میباشد که با نتایج این پژوهش تطابق ندارد. بنابراین بر اساس نتایج این پژوهش میتواند مناطق زیر کشت موز در استان افزایش یابد.

چکیده [English]
Banana growing areas are located in subtropical climates between 20 and 30 degrees north or south of the equator. Considering that Sistan and Baluchistan province is located in the latitude of 25 to 31 degrees north, it can be suitable for banana cultivation. In this regard, the main goal of this research is to identify the climatic potential of Sistan and Baluchistan province for banana tree cultivation using agroclimatic indices. In this study, two methods of AHP and Boolean logic of the province's climate were used to evaluate the agroclimatic indices including growing degree days (GDD), biologically effective degree days (BEDD), sum of active temperatures (SAM), cumulative temperature difference (TD), water vapour pressure deficit (WVPD), and potential evapotranspiration (PET). The results of the research showed that with the AHP method, 17% of the area of the province (Dashtiari, Chabahar, Konarak and Zarabad cities and parts of the south of Rask, Qasrqand and Nikshahr cities) is very suitable for banana cultivation and 8% is suitable for banana cultivation (northern half of Sarbaz, Rask and Nikshahr counties). Also, the results of this research showed that in Bolin logic, 10% of the studied area (Dashtiari, Chabahar, Konarak and Zarabad cities and parts of the south of Rask, Qasrqand and Nikshahr cities) are suitable for banana tree cultivation in the province. Currently, banana cultivation areas are less than 1% of the area of the province, which is not consistent with the results of this research. Therefore, based on the results of this research, the areas under banana cultivation in the province can be increased.
